I received my soil test today in the mail. Very pleased, but wanted some opinions, I'm thinking Nitrogen is low and Potash. The numbers are as follows:

Organic Matter 16.8
Nitrogen No3-N ppm - 20
Phosphorus Weak Bray ppm - 136
Phosphorus NaHCO3-O-304
Potassium - 240
Magnesium - 476
Calcium - 4245
Sodium - 11
Sulfur - 623
Zinc - 13.5
Manganese - 9
Iron - 27
Copper - .8
Boron - 2.5

Soil PH 7.0

I realize I need to add Nitrogen and Potash and am prepared to do that. It also said to have organic matter tested before application, is there a reason?

Thanks in advance for any recommendations/suggestions.

This is per 1200 sq ft patch. I increased the patch to 2400 sq ft. and have not amended that yet. I did get a soil test on the un-amended portion of the patch. Surprisingly not bad in numbers.

Wow, the OM is really high. Good thing you have lots of Ca, that should help prevent splits, but you are still in danger of blowing pumpkins up.

I would add a bit of K, but not sure you need anything more than that.

Use sulfate of potash. Other than that things look great.

Weak Bray ppm - 136
Phosphorus. Your phosphorus is really high. Just add potash. Other wise, your soil looks great

I agree sulfate of potash (0-0-50). I suggest 8-9 lbs/ 1000 ft2. I would also add some Kelp Meal, 50 lbs/ 1000 ft2 and humic acid at 25 lbs/ 1000 ft2. Don't work it wet. Keep the weeds out and grow a big one!

In a related subject, how does one convert ppm to lbs./A?

lbs/acre = ppm * 2

Thanks. I'm assuming x 2?
